Leica Macro-Elmar-R 100mm ƒ/4 Photography Lens with R-Mount
Overview
The Leica Macro-Elmar-R 100mm ƒ/4 Photography Lens with R-Mount is a telephoto prime introduced in the 1970s. A telephoto field of view compresses distance and separates a subject from its background, the range portrait and sports photographers work in. The ƒ/4 maximum aperture performs best in well-lit environments and suits subjects that want greater depth of field, closing down to ƒ/22. Its multi-coated elements suppress internal reflection better than the single-coated glass of the same period. The Leica Macro-Elmar-R 100mm ƒ/4 is a full-frame lens native to the R-Mount system.
